Topic: Need some advice on which board/modules to use for a remote controlled light (Read 508 times) previous topic - next topic


Hi guys,

I'm fairly new to Arduino (and programming and DIY electronics in general), so I'm looking for some advice on a small project i'd like to do.

Basically it's going to be an LED light for my bedroom that I'd like to be able to turn on and off without having to get out of bed =).

I'm planning to use a few (6?) white LED's, and then one each of red, blue, and green I think.  I'm going to set it up so that it can either be on as white LED's (possibly with 2 levels of brightness by turning on 3/6 of the LED's) and also slightly tinted by the colored LED's (whites on as well as one of the colors).  I'm fine with the programming and hardware using a normal switch but I'd like to be able to do it using either my iPhone, or a small remote.

However, I've never built anything that communicates like that before.  I had thought that since my phone is bluetooth capable, that would be the easiest way to communicate with the lights, but I'm not really sure.

I was looking to use the smallest/cheapest board I could find that will be able to control all of the lights from a 9V battery.  I think an Arduino Pro Micro board from Sparkfun (https://www.sparkfun.com/products/11098) might be my best bet, but again, I don't have much experience with any of this.  I'd prefer the board to be USB programmable so I don't have to fool with the serial connections.

As for a bluetooth module (I'm totally open to other options if there's something easier/cheaper/better) I'm kind of in the dark as I've never done anything like this.

Any advice you guys could provide would be much appreciated!





After doing some more reading, I think I'm going to use an IR remote and sensor for the control since they're so cheap.

Any thoughts on the best board to use?  I'd love something like http://digistump.com/ but they're not available yet =(


if you are going to use an IR remote check out this project:


If helped me become familiar with IR tech.


You are going to have to get out of bed, often,  to change the battery.
